Question

In periodic table, which period have most electronegative elements?

• A. $1$
• B. $2$
• C. $3$
• D. $4$
• E. $5$

Answer 1

The correct option is B $2$

In general, electronegativity increases on passing from left to right along a period and decreases on descending a group. Fluorine is the most electronegative of the elements which belong to period 2 of the periodic table.

Along with fluorine, oxygen, nitrogen also has high electronegativity.

Hence, the correct option is $\text{B}$
